Type of Unit: Introduction
Students should be able to:
- Understand ratio concepts and use ratios.
- Use ratio and rate reasoning to solve real-world problems.
- Identify and use the multiplication property of equality.
This unit introduces students to the routines that build a successful classroom math community, and it introduces the basic features of the digital course that students will use throughout the year.
An introductory card sort activity matches students with their partner for the week. Then over the course of the week, students learn about the routines of Opening, Work Time, Ways of Thinking, Apply the Learning (some lessons), Summary of the Math, Reflection, and Exercises. Students learn how to present their work to the class, the importance of students’ taking responsibility for their own learning, and how to effectively participate in the classroom math community.
Students then work on Gallery problems, to further explore the resources and tools and to learn how to organize their work.
The mathematical work of the unit focuses on ratios and rates, including card sort activities in which students identify equivalent ratios and match different representations of an equivalent ratio. Students use the multiplication property of equality to justify solutions to real-world ratio problems.
